docker-compose安装redis高可用哨兵集群（一主二从三哨兵）

以redis 7.0为例子

直接上代码

docker-compose.yaml

version: '3.3'
services:
  master:
    image: redis:7.0
    container_name: redis-master
    #restart: always
    command: redis-server --port 6379 --requirepass root  --appendonly yes --masterauth root --replica-announce-ip 192.168.2.168 --replica-announce-port 6379
    volumes:
      - ./data/master:/data
    ports:
      - 6379:6379
  slave1:  
    image: redis:7.0
    container_name: redis-slave-1

    volumes:
      - ./data/slave1:/data
